Configuring the Source: Message Filter

The next step is to configure the Message Filter source component:

  • In the Incoming Channel Name field, select a valid incoming channel definition from a choice list.
  • In the Filter Index (sub-channel ID#) field, select the sub-channel to use from the incoming channel.
  • In the Poll Time (milliseconds) field, specify the number of milliseconds between subsequent queries to the database for the next outgoing message with the "waiting" status.
  • Leave the Full filter VMD path (req. to transform and ignore) field blank.
  • Select the No Transformation option.
  • Leave the Ignored messages field blank.
  • In the Error Handling field, select Skip Message. This ensures that the channel will not stop if an error occurs.
  • In the Automatically purge error logs older than field, specify when logs will be stale and can be deleted.

  • Click the Add Channel button to add the channel to the Iguana dashboard.
  • Click the Export Database Tables link.
  • Check Channel Log Tables, and click Export Tables. The tables are exported to the applicable database API.

You can leave everything else as is. You only need to configure the other fields if you want to do scripted transformation or ignore functions, all of which is covered in the HL7 Transformation tutorial.
